The scheme is adopted: as can be seen from fig. 7 and 8, the outer wall of the elastic clamping block 30630 is provided with a spring for pushing the abutting plate 3062 to pop out outwards, meanwhile, a chamber allowing the elastic clamping block 3062 to move is formed in the rectangular plate at the lower end of the abutting plate 3062, when the first chain 3052 rotates clockwise through the gear shaft 307 to cause gradual rolling of the first chain 3062 and drive the elastic stabilizing member 3051 to turn upwards, the second chain 3031 is in a gradual loosening state on the surface of the gear shaft 307, one end of the elastic stabilizing member 3051, close to the immersed tube tunnel housing model 200, is abutted by the immersed tube tunnel housing model 200 and gradually moves towards the direction close to the first chain 3052 and presses the top end of the rubber inclined block at the upper end of the abutting plate 3062 to enable the rubber inclined block to move downwards to the outside of the notch of the elastic stabilizing member 3051, at this moment, the abutting plate 3062 is pushed to abut against the outer wall of the immersed tube tunnel housing model 200 by the spring 3062 by the spring of the outer wall of the elastic stabilizing member 3032, otherwise, when the gear shaft 307 rotates anticlockwise, the second chain 30131 rolls on the surface of the second chain 3031, and the elastic stabilizing member 3031 is not in an overall abutting state with the immersed tube tunnel housing model 200, and the elastic stabilizing member 3031 is pulled against the inner side of the elastic clamping block 3031.
